“…Electromagnetic pollution and information leakage have become increasingly prominent with the widespread use of electrical and electronic equipment. [1][2][3][4][5][6] Electromagnetic pollution can interfere with the regular operation of peripheral equipment and induce various diseases; information leakage can cause considerable losses to individuals and even the country. Therefore, there is an urgent need to develop efficient electromagnetic interference (EMI) shielding materials to solve these problems.…”

Isolation structure has been proven to be an effective method for constructing electromagnetic shielding composites, achieving high electrical conductivity with shallow filler content and high-efficiency electromagnetic shielding. However, there are still many challenges in further optimizing the design and improving absorption. This article designed a hybrid isolation structure using nylon magnetic microspheres and polystyrene (PS). First, we prepared PA magnetic microspheres (Ni@PA6M) with Ni nanoparticles uniformly dispersed by the reaction induced phase separation (RIPS) method, then mixed with MWCNT and PS at high speed and formed by hot pressing. Under the opti-

“…Many recent studies have shown that exposure to EMR is causing health hazards for human beings, plants and animals [ 2 , 3 , 4 , 5 ] at levels well below most of the accepted international guidelines [ 6 ]. The damage goes well beyond living organisms, and includes disruption of the functionality and performance of many electronic devices, slows down their efficiency and degrades the reliability, lifetime and safety of electrical equipment [ 7 , 8 , 9 ].…”

An efficient, low-cost and environmental-friendly method to fabricate magneto-active fabrics (MAFs) based on cotton fibers soaked with silicone oil and iron oxide microfibers (mFe) at mass fractions 2 wt.%, 4 wt.% and 8 wt.% is presented. It is shown that mFe induce good magnetic properties in MAFs, which are subsequently used as dielectric materials for capacitor fabrication. The electrical properties of MAFs are investigated in a static magnetic field with intensities of 0 kA/m, 160 kA/m and 320 kA/m, superimposed on a medium-frequency electric field. The influence of mFe on the electrical capacitance and dielectric loss tangent is determined, and it can be observed that the electrical conductivity, dielectric relaxation times and magnetodielectric effects are sensibly influenced by the applied magnetic and electric fields. The results indicate that the MAFs have electrical properties which could be useful for protection against electromagnetic pollution or for health monitoring.

“…Since more and more commercially available electronic devices have been put into practice, more and more harmful electromagnetic radiation (EMR) has been accumulated in the surrounding. A lot of studies have been published, which describe negative impact of EMR not only on the functionality of electronic devices, 1,2 but also on human beings health. 3,4 Thus, the necessity of shielding of EMR has become more pronounced over last decades.…”

Ethylene propylene diene monomer rubber was filled with multi-walled carbon nanotubes to prepare composite materials with the effect of electromagnetic radiation (EMR) shielding. Sulfur-based curing system as well as peroxide curing system were used for vulcanization of rubber compounds. The main goal of the work was the investigation of curing system composition and filler content on curing process, physical-mechanical properties, cross-link density, and shielding efficiency of the prepared composites. The results showed that curing characteristics and cross-link density of composites were dependent on both, amount of carbon nanotubes and curing system composition. The incorporation of filler resulted in the enhancement of physical-mechanical properties of composites. Higher values of tensile strength were found to have composites cured with organic peroxide in combination with coagent. The achieved results also demonstrated that carbon nanotubes filled rubber composites are suitable candidates for applications, in which shielding of EMR at low frequencies is based on reflection.
